SAFETY APPLIANCE FOR POVVDER-KEGS AND GTI-IEEl CONTAINERS.

Specification of Letters Patent.

Patented Apr. 2d, i917.

Application led April 9, 1915. Serial No. 20,197.

To all whom t may concern:

Be it known that l, BARDOLPH PETERSON, a citizen of the United States, residing at Sherrard, in the county of Mercer and State of illinois, have invented certain new and useful Improvements in Safety Appliances for Powder-Kegs and other Containers, of which the following is a specification.

This invention relates to improvements in safety appliances for powder kegs and other containers, and one of its chief objects is to produce an attachment that may be readily fitted to the seat-plate of powder kegs when the keg caps have been removed and which is retained in position by merely turning up the loose end of the cap seat. Nhen in position upon the powder keg the attachment serves as an absolutely safe filler for cartridges which may be filledl in one operation and in an upright position and without the usual necessity of the operator placing his hands upon the cartridge during the filling operation or the necessity of tamping the cartridge during the filling operation. The device comprises a cone-shaped portion and a valve arranged therein to admit or cut off a supply of powder from the keg to the cartridges, the valve being manually operated by a resilient finger rod connected thereto. The mouth or top of the cone-shaped portion of the device is well above the hole in the powder kegand this mouth is intended for deep insertion into the mouth of the cartridge thereby avoiding the possibility of any grains of powder' being blown about during the filling operation. rlhe shape of the attachment is such that when a quantity of powder has been admitted to the coneshaped portion from the powder keg this powder will serve to hold the powder in the keg back, or to choke the flow of powder from the keg in a measure, so that the keg may be tilted at quite an angle thereby giving the operator plenty of time to see that the attachment is properly disposed in the mouth of the cartridge before the powder really begins to flow. When he is fully satisfied that proper connection with the cartridge is made he may turn the keg upside down and permit the powder to run, with full force, into the cartridge until the same is filled. When the cartridge is filled the keg may be slowly turned back to upright position and set again upon the bottom, or floor, with the absolute certainty that no powder has at any time been exposed. In the operation just described the shape of the attachment causes the powder therein to again choke off the flow from the keg before the connection with the cartridge is broken and the powder remaining in the filler will drop back into the keg with safety.

The construction of my attachment is such that the filling operation is most satisfactorily performed without the customary flap or slide; the operator need not watch the cartridge to see that the powder runs into the same nor need he be on the alert to check the flow of powder at the proper time as this is accomplished automatically and compliance with the statutes requiring him to keep his light at a distance while filling is rendered easy. lNith only ordinary care cartridges may be filled by the light of the ordinary carbid pit lamps in position upon the miners cap.

Willen the valve is closed in the attachment a positive seal for the keg is provided and the usual danger constantly overhanging a mine or storehouse due to poorly sealed powder kegs is avoided. Very often an explosion in a mine or` powder room will jar the plugs vout ofvpoorly secured kegs and permit the powder therewithin to ignite; the construction of my improvement, further, is such that trains of powder or dust are not likely to form upon the cover plate of the keg, or should they be dropped thereon they cannot communicate a spark to the powder within due to the fact that my attachment renders the keg practically air and water tight.

TVith the foregoing and other objects in view-the invention consists in the combination and arrangement of parts to be hereinafter fully described in the following specification, pointed out in the claim and illustrated in the accompanying drawings which form a part of said specification and in which- Figure l is a side elevation of the preferred form of the device showing the method of applying it to the powder keg; the dotted lines showing the application completed.

Fig. 2 is an inverted plan view of the attachment shown in Fig. 1.

Fig. 3 is a top plan view of a portion of a powder keg with the attachment removed.

Like reference characters indicate corresponding parts throughout the several views.

Referring to the drawings, the reference letter A designates the powder keg.

My' attachment comprises the approximately cone-shaped member or tapered filler 1 formed with the inwardly bent base edges 1a and the outwardly bent base edge 1"; the shape of the base of the member 1 being approximately the same as the shape' of the cap-seat-plate 9 carried by the keg so that the member 1 may be slipped over the said plate, the base edges 1 of said member sliding beneath the edges of said plate, and thus attachedto the face of the keg; the base edge 1b of the member 1 riding over the cap-seatplate 9 for engagement with the upturned broad edge 2 of said plate; the narrow edge 9l of the plate 9 may now be turned up as shown in Fig. 1 to hold the attachment in place. The plate 9 is secured around the edges of its opening to the cap-plate of the powder keg by means of flanges 3 extending from the latter, at the edges of its opening, upwardly and bent downwardly upon the plate 9. A valve 4 is hinged upon the resilient finger rod 5 which is journaled in the lower portion of the` member 17 said finger rod terminating beyond the member 1 in an operating handle 6 adapted, when the valve is in closed position, for frictional locking engagement with the lower notched portion 7 of a keeper 8 secured to the outer periphery of the said member 1; when the valve is in open position the finger rod may be releasably locked in engagement with the notched portion 7a of said keeper.

The purpose of the valve l is to serve as a closure for the powder keg while the powder is stored therein as this valve is so shaped as to fit snugly in the opening in the face of the standard keg as clearly shown in Fig. 1.

lWhen it is desired to pour powder from the.

keg into a cartridge, the valve is raised or opened and the keg raised oif the bottom, and, as the keg is tipped over, the powder will ovv through the open valve into the member l and out through the top or small end of the same which is inserted in the cartridge.

When the cartridge is lled the keg, still in the arms of the operator, may be gradually righted and the flow of powder from the keg will be automatically cut off by the powder in the attachment which powder will then drop back int-o the keg with safety as the keg assumes an upright position.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as defined in the appended claim.

What is claimed is A cartridge-filler attachment for powder kegs and other containers, including an approximately cone-shaped spout, said spout having inwardly bent flange-forming edges and an outwardly extended plane-edge, said i keg having a seat-plate provided with an opening, a valve forming a closure for said opening, said seat-plate having an upturned edge and an extended narrow edge, said upturned edge being adapted to receive the eX- tended plane-edge of said spout and said narrow edge extension of the seat-plate being adapted to be bent upwardly to lock the spout tothe container.

In testimony that I claim the foregoing as my own have hereto afliXed my signature in the presence of two subscribing witnesses.

BARDOLPH PETERSON.
